IMPROVEMENT lIN RESERVOIR COOKING-STOVES.

Specification forming part of Letters Patent No. 153,144, dated July 14, 1874; application filed February 3, 1873.

To all whom it may conocia:

Beit known that I, GURDoN G. WoLEE, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Cooking-Stoves 5 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this. specification, in which- Figure l is a vertical section from front to rear on line a' x of Fig. 3, showing the prod ucts of combustion impinging upon the front of the reservoir and the back of the oven. Fig. 2 is a like section on line Q/ y of Fig. 3, showing the reservoir cut off from products of combustion and the rear oven-plate exposed to same. Fig. 3 is a perspective view, showing the stove with top plate and water-reservoir removed and the several rear lues and dampers.

The design of the present invention is to provide suitable passages or nues and apertures therein or communicating therewith in a sto ve, through and by means of which the products of combustion may be directed by dampers, so as to be thrown upon the inner front of the waterreservoir, or upon the back wall or plate of the oven, or upon both, or upon neit-her as may be desired and to this end it consists of a rear chamber or lue having openings in its front wall, which is the rear vertical end plate of the stove, communicating with the descending liuc or ilues of the stove, and with such arrangement of dam pers as will cause the products of combustion in their passage round the oven to be directed into said chamber or flue or excluded thence at will; and it further consists of a chamber or flue passage located at the rear of the vertical end plate of the stove, and communicating with the lues thereof by means of apertures or openings in said plate, the front wall of the water-reservoir, which is attached to the rear of this chamber or flue, constituting the rear wall of said chamber, while, by suitable dampers, the tlow of the products of combustion through the said lues, chamber, and apertures is regulated and controlled, in the manner and for the purposes hereinafter more fully explained.

ln the drawings, A represents a cookingstove, provided, as usual, with a fire-box in front, an oven, Ste., and otherwise of the common and ordinary construction well known to the trade, except-in g inl the details and special arrangements or adaptation of the present invention. B is the waterreservoir, set, placed, or adjusted at the rear of the chamber or tlue C, in any convenient and workmanlike manner to make it firm and secure in position. Thus placed and adjusted its front wall constitutes the rear wall of the said chamber or flue. D is the central vertical end lue, and D/ D the side vertical end iiues.

By this construction it will be seen that the chamber or flue G is a supplemental or additional chamber at the rear of the stove.

Then the damper d is in a horizontal position the products of combustion will escape direct from the main top ue a through the exitpipe at F. Vhenv dampers e e and d are in vertical position the products of combustion will dive through the end or side passages or lines D D', and finally escape through the central ilue or uptake D and exit-pipe. By this means it will be perceived that the usual functions and operations of the stove can be carried on without heating the water-reservoir B, since there will then be no draft through the apertures e, and consequently the chamber (l will constitute in fact a non-conducting medium or space between the hot lines and the said reservoir; but when it is desired to turn the full force of the heat, &c., upon the front of said reservoir the damper d is placed in vertical position, the dampers e e are turned down upon the end or side lues D D', and the damper e is opened or placed in horizontal position then the products ot' combustion flowing from the main top tlue pass through the side openings in end plateE, caused or made by turning down said dampers e e', and, entering the chamber C, impinge at irst upon the front wall of the reservoir, and then circulate freely in said chamber, heating it thoroughly, and inally escape through the central aperture, where the damper e is turned down, into the uptake D and to the exit pipe. In this manner and by this means the said water-reservoir can be quickly heated when desired. When there is occasion to use both the oven and the water-reservoir at the same time, both can be easily heated by closing the dampers d and --that is, placing them in vertical position and turning down or horizontally dampers e e', the products of combustion will then pass from the main top flue in the rst instance into the chamber C, and thence escape by the side openings e into the side diving-fines, and finally pass o through the central passage or uptake D. In this passage the front of the water-reservoir will be heated by the inflowing current of the products of combustion7 and, also, the rear Wall of the oven will receive a large share ofthe heat from this current as it impinges upon itin escaping from chamber C.

Having thus fully set forth the nature and merits of my invention7 what I claim as new 1s ues, in the manner and for the purposes set forth.
